We wanted to take a hot shower but there was no hot water at all. We asked someone to fix it and he showed us that there was a heating switch outside the bathroom which would turn on the boiler.They were floating in self made tubs and rowed with sticks. When they reached our boat they tried to sell us beverage. We vigorously denied them access to our boat. It just did not help.At around 6pm. we were back at the Chilean border and we were happy to change cars (to the mini bus again) and seeing a paved road. It took us another hour to get back to our hotel.
